Fire-extinguishing powders based on ammonium phosphates (FEP) have a high specific fire-extinguishing ability. However, during storage, their technical characteristics deteriorate, which reduces the efficiency to extinguish fire. To solve this problem, authors considered promising direction for improving properties of FEP by using superhydrophobic functional additives silicon dioxide particles....

Fire protection is a basic safety issue for all categories of buildings. The criteria effective fire suppression and the characteristics extinguishing systems in insulated areas depend on combination factors. main influences include type combustible material, ambient temperature, spray extinguisher, air inflow outflow conditions, space geometry. This article analyzes most widely used fire-extin...

Forest fire evolution plays an important role in the decision-making of controlling the forest fire. This paper aims to simulate the dynamics of the forest fire spread using a cellular automaton approach. Having analyzed the characteristics and evolution of forest fires, a simulation model for the forest fire evolution based on the energy accumulation and release is proposed. And, taking Austra...

Agent-based simulations enable the simulation of social phenomenon by representing human behaviors using agents. Human actions such as evacuating to safe havens or extinguishing fires in disaster areas are important during earthquakes. The inclusion of human actions in calculating the damage at disaster sites provides useful data to local governments for planning purposes. In order to practical...

Fire is a dominant disturbance within many forested ecosystems worldwide. Understanding the complex feedbacks among vegetation as a fuel for fire, the effects of fuels on fire behavior, and the impact of fire behavior on future vegetation are critical for sustaining biodiversity in fire-dependent forests. Nonetheless, understanding in fire ecology has been limited in part by the difficulties in...

Automatic fire detection is important for early detection and promptly extinguishing fire. There are ample studies investigating the best sensor combinations and appropriate techniques for early fire detection. In the previous studies fire detection has either been considered as an application of a certain field (e.g., event detection for wireless sensor networks) or the main concern for which ...
